IMPROVEMENT lN IRON TANKS FOR HOLDING PETROLEUM.

Specification forming part of Letters Patent No. 210,324, dated November26, 1878; application filed October 7, 1878.

To all whom it may concern:

Be it known that I, ELI E. HENDRICK, of (Jarbondale, in the county ofLackawanna and State of Pennsylvania, have invented a new and valuableImprovement in Iron Tanks for Holding Petroleum and other Liquids; and Ido hereby declare that the following is a full, clear, and exactdescription of the construction and operation of the same, referencebeing had to the annexed drawings, making a part of this specification,and to the letters and figures of reference marked thereon.

Figure 1 of the drawings is a representation of a side view of myimproved tank, and Fig. 2 is a vertical central section thereof.

The nature of the invention consists in the construction and novelarrangement of an iron oil-tank made of sections riveted together, andhaving the interior lapjoints and rivet projections plastered with acement filling, and covered with a lining of cloth or paper cemented tothe interior of the tank, and covered with a water and oil proofcomposition, as hereinafter shown and described.

In the annexed drawings, the letter A designates the body of the tank,which is constructed of iron of less thickness than that ordinarilyemployed. To the inside surface of the tank the lining b is secured by asuitable cement. A cementI find to answer the purpose is composed of onepart of red lead to two parts of linseed-oil, boiledtogether until allthe leadis dissolved, and applied hot to the inside of the tank, andalso to the lining. This lining may then be secured to the wall of thetank by simply brin gin g it to place and thoroughly rubbing it down.This cement adheres strongly, and resists water, petroleum, and otheroils.

The sheets of lining should overlap each other, so that the said liningwill be continuous and without flaw.

If paper is used as a lining, it is coated over with any suitablecovering--as, for instance,

a paint composed of linseed-oil, red lead, and hydraulic cement or lime.Two or three coats of this paint render the paper absolutely oil andwater proof. A coating of boiled coaltar has proved very effective forresisting either oil or water.

The paper used is a good strong Manila stock or other fibrous paper, andI may sometimes use that quality known as leatherpaper, the same beingboth cheap and strong.

When oil or rubber cloth is used no coating is necessary;

In lining iron tanks it is not absolutely requisite to cover the entireinterior surface of the tank. It will suffice if the laps or joints andheads of the rivets are well covered.

To overcome the difficulty of covering with paper the projections causedby the laps and rivets, the jointand rivet-heads are carefully plasteredover with a cement made of red lead, hydraulic lime, and linseed-oiluntil a swell is formed, to the shape of which the paper will readilyadapt itself.

The advantages of a tank constructed as above are obvious. In iron tanksas commonly constructed the metal must be of snflicient thickness toallow the joints to be calked, as in boiler-making, in order to preventleakage, although, for strength, one-tenth of the thickness wouldperhaps be sufficient; but by lining the joint I dispense with calking,and am able to use iron of just sufficient strength to hold the contentsof the tank, thus greatly lessening its cost and weight.

Furthermore, the workmanship of the tank need not be of such a superiororder, as strength only is required, the oil-proof joints beingperfected by the lining.

I am aware that wooden oil-barrels have been saturated with silicacompounds to prevent contraction and expansion, and then lined also,that petroleum'tanks have been made mainly of paper or paper-pulpcovered with a wooden casing, and freely separable along the joints ofthe staves of the outer casing. I do not claim such construction.

What I claim as new, and desire to secure by Letters Patent, is

An iron oil-tank made of sections riveted together, and having theinterior lap-joints and rivet projections plastered with a cementfilling, and covered with a lining of cloth or paper cemented to theinterior of the tank, and covered with a water and oil proof composition, substantially as specified.

In testimony that I claim the above I have hereunto subscribed my namein the presence of two witnesses.
